Sometimes what’s wrong with your air conditioning and heating system really doesn’t require the service of an expert repair person. Here are some common troubleshooting tips to go over before you call for a repair. A/C Not Cooling or Blowing? Check circuit breakers at fuse box. The outdoor condenser unit and indoor air handler unit have their own breaker. Even if breakers appear to be in the correct position, they are often tripped. Flip circuit breaker off and back on. Indoor A/C Unit Leaking Water? If the unit is leaking water one of three possible things has occurred Drain line is plugged. Check to see if your A/C drain line outside your home is draining properly. If it is not you can clear it by attaching a wet vacuum to the outside. Evaporator coil is dirty. Dirt, mold, and algae are growing on your coil causing it to drip> Coil is frozen with ice. Your A/C is probably low on freon. You will need to turn off the A/C and call for service.

In the warmer room, make sure the vent is open or open it further. If this does not resolve the problem, the situation is the result of one of the following three conditions. The ductwork was not sized properly The system needs to be balanced by adjusting the air flow dampers in the grills The ductwork has come apart and is leaking cool air into the attic. Thermostat Not Registering Correct Temperature? A temperature reading of within three (3) degrees up or down is considered normal. New digital thermostats are more accurate. Musty or Mildew Odor? Your ductwork got wet and is giving off a musty odor or it’s possibly growing mold.

No filters were used and the ductwork is dirty and growing mold. No filters or wrong filters were used and evaporator coil is plugged up with algae, fungus, mold and bacteria.

This build-up will restrict your air flow and cause you to have less cooling throughout your house and, at the same time, increase your electric bill. The bacteria and mold spores will circulate through your entire home and possibly affect your allergies and your health.The only way to fix this problem is to have the coil professionally cleaned. Why Should I Choose a Programmable Thermostat? Most programmable thermostats are capable of four different time and temperature settings. A programmable thermostat will reduce your power bill by fluctuating temperature settings while you are at work, away or asleep.We highly recommend this product. Is a yearly Tune-Up necessary? All A/C units should be maintained at least once per year. Burning Smell on Heat Mode? Check the circuit breakers at fuse box. Please note that when using your heat for the first time in cool weather, you may smell a slight burning odor. Dust has accumulated over the months and is burning off the heating coils.

This is normal and should last no more than 30 minutes. No Heat Coming Out of the System? Make sure the heating temperature is set above the room temperature. Check to make sure the thermostat is set to “Heat” and “Auto” position. Flip your circuit breaker off and back on. Some units can take 60 to 90 seconds before the heat cycle turns on. If you’ve allowed ample time and still no heat, turn your thermostat to the “OFF” position and call for service. Heat From System is Not Warm Enough? Make sure the temperature is set above the room temperature. As air circulates through the system, repeatedly, it will get warmer. If you have had your heat on for over 3 hours and it’s still not getting warm you need to call for service. Make sure the thermostat is set to the “Auto” position. If the actual temperature is above the temperature set, call for service. If the actual temperature is below the temperature set, the heat will continue to run until it reaches the temperature for which it is set.

If you find it hasn’t shut off after reaching the requested temperature, call for service.

Obviously this was a serious problem that needed to be corrected immediately. Not only are sewer gasses an unpleasant experience but they can be a safety concern. If you smell sewer gasses in your home you should try and diagnose the problem sooner than later.I started quizzing my friend about any recent changes in their home that might have contributed to the sewer smell. He asked me if washing machine mold might be causing the smell or some type of dead rodent.

He wasn’t sure that anything had changed other than they had recently purchased a new washing machine. I knew there was likely something wrong with the plumbing trap (p-trap) which was accounting for the sewer gas smell.The culprit ended up being the washing machine hose that was incorrectly installed by the appliance delivery guys. Read on to see what happened!Plumbing traps (p-traps) create a trap in the drain pipes which retain a small amount of drain water which in turn creates a water seal to prevent sewer gasses from entering the living space of buildings. Traps come in several different configurations but they all work the same way by trapping water in the pipe to seal out the sewer gasses. Traps are present for all sinks, showers, toilets and drains (such as washing machine drains).Today most washing machines come supplied with a flexible, corrugated plastic drain hose. The hose is easily inserted into a standard washing machine drain box (see photo). The washing machine drain box is hooked up to the houses waste piping that contains a P-Trap inside the wall (or exposed in older homes).

With this set-up waste water comes out of the plastic washing machine hose and empties into the drain box pipe. The waste water fills the trap below and creates a seal that prevents the sewer smell (gasses) from entering the home. See the next diagram for a typical washing machine drain set-up.The following diagram shows what happened at my friends house. The delivery guys from the appliance company delivered the new washing machine and hooked it up. The ended up pushing the flexible plastic washing machine drain hose into the drain box and past the P-Trap.As you can see in this diagram the flexible washing machine drain hose prevented waste water from filling the trap. This allowed the sewer gasses to pass around the house and trap and into the house. To fix this problem all he had to do was pull the washing machine drain hose out of the drain box until it was only inside by about 8 inches or so.Obviously this was a rare situation and one that I’m still scratching my head about. For the life of me I can’t figure out what the delivery guys were trying to do.
